What is the mass of 4.56 moles of copper (ii) fluoride

musickatia [10]

Answer:

463.0 g.

Explanation:

We can use the following relation:

<em>n = mass/molar mass.</em>

where, n is the mass of copper(ii) fluoride (m = 4.56 mol),

mass of copper(ii) fluoride = ??? g.

molar mass of copper(ii) fluoride = 101.543 g/mol.

∴ mass of copper(ii) fluoride = (n)(molar mass) = (4.56 mol)(101.543 g/mol) = 463.0 g.
